Pythagorean theorem should help with your question so try that and let me know if you don't understand it
Y= -3x+7 im pretty sure this is the answer
Answer: -5x+y=6
Step-by-step explanation:
Given
Points on line 
The standard form of an equation is 
Using the two-point form of a line

Answer:
(-2, 3)
Step-by-step explanation:
<u>Substitute 2x + 7 for y in y = -2x - 1</u>
- <u></u>

Add 2x to both sides
Subtract 7 from both sides.
Divide both sides by 4.
<u>Substitute -2 for x in y = 2x + 7</u>
- <u></u>

Simplify both sides.
Therefore, the answer is (-2, 3).
